Definitions

  • the distribution unit can have a plurality of outputs for connecting the distribution unit to a plurality of brake circuits, for example also to a parking or trailer brake circuit.
  • a reliable application of the control pressure to the foot brake module connection can be ensured.
  • this enables a relatively simple integration of the valve unit into the pneumatic system of the air treatment unit, which lowers the production costs of the air treatment unit.
  • the foot brake module connection and the valve unit located in between are also connected at the same time to the storage container of this consumer circuit.
  • This connection is also functionally relevant because there is a volume behind the output pressure so that the pressure in front of the control valve does not collapse when the pressure increases. In this respect, the volume of a storage container that is not present in front of or in the distributor unit is also relevant for the function.
  • a valve unit that is electrically controlled by the air preparation unit but supplied with compressed air supply outside the preparation housing is also conceivable.
  • Figure 1B shows a valve unit 110 configured in this way in which the line 113 is vented in the de-energized state due to the arrangement of the two solenoid valves 200 normally open and 210 normally closed, which This is necessary due to the system, so that in the normal case, ie in the case that the valve unit 110 is de-energized, the automatic braking system does not superimpose the driver's request).
  • the valve unit 110 is connected to the filter cartridge line 107 via a distributor unit 112.
  • a connecting line 113 connects the distributor unit 112 to a foot brake module connection 114 of the housing 108.
  • the valve unit 110 is arranged in the connecting line 113.
  • the connecting line 113 is designed as part of a brake circuit assigned to a service brake of the brake system 100.
  • the arrangement of the electronic brake control in the air treatment unit 102 which is already present, saves the use of additional components which would otherwise have to be provided in different assemblies of the brake control unit.
  • the electronic brake control can thus also be present or designed redundantly in the electronic air preparation system.
  • synergies can be used that result from the components located in the air treatment unit 102, such as the integrated parking brake.
